Case Study: Johor Bahru E-Mobility Service Provider Sourcing Success

The inquiry arrived on a Tuesday; by Friday a sample was on a plane. The margin squeeze in the category pushes buyers toward factory-direct programs with type-test evidence.

After a 30-day pilot at two sites, Budi Santoso selected Wanlin as their EV charging manufacturing partner. The contract went to the factory that could show RCD trip-time data and sealed enclosures, not the lowest quote.

• SMT lines run three shifts and every charging board gets an automated function test before enclosure
• OCPP 1.6J conformance is verified against a reference CSMS and the log travels with the shipment
• OCPP builds support buyer-specified CSMS endpoints, security profiles and custom DataTransfer messages

The monsoon test bench sprayed the cabinet for an hour and the IP54 gaskets kept the board dry.

Problem Analysis & Field Report: Why Global Buyers Need 20-Socket Community Charging Station

Nobody flagged it at the packing station; the market flagged it first. A school district rejected a low-bid station because a single fault took all twenty sockets down at once.

Field case: A market cooperative in Johor Bahru moved from a flat cash box to the WL-CS20 with per-port metering and daily settlement exports. The utility bill reconciled within 2% of the meter log for the first time, and the co-op raised a 31% margin on metered charging within one season.

Why it matters for global buyers:

• single-rail busbars melt when every socket draws at once
• the fix was twin load groups with per-port breakers
• daily settlement exports turn charging into an auditable revenue line

Certified EV Charging Manufacturing for Global Markets

Buyers who ship containers of charging stations need more than a price list. The production and QC flow below is what lets a distributor open a carton and trust what is inside:

• SMT lines run three shifts and every charging board gets an automated function test before enclosure
• OCPP 1.6J conformance is verified against a reference CSMS and the log travels with the shipment

Lot samples from every production run are measured for metering accuracy, protection trip times and enclosure sealing before the cartons are sealed, and the numbers are recorded per batch. A buyer can request those records with any order.

EV Charging OEM Process: From Inquiry to Shipment

Here is the step-by-step path the order took, with the checkpoints that kept quality on track. A standard charging station OEM project then follows 8 steps:

1. Tell Us Your Target Market - Southeast Asia, the Middle East, Europe, North America, Africa or Latin America; each market may require different certifications, socket standards, voltage classes and manual languages
2. Select a Model Line - our team recommends WL-series platforms for your channel and price band, or works from a reference unit you send
3. Verify Documentation - request certificate files, OCPP conformance logs and test reports for the exact model before you commit
4. Confirm Customization - cabinet colors, logo, firmware behavior, tariff logic, payment flows and packaging
5. Sample Evaluation - verify meter accuracy, load balancing and CSMS integration on real samples before scaling
6. Confirm Production - after specifications, commercial terms and OEM details are locked
7. Quality Inspection - lot samples are tested and every finished station passes hipot, trip-time and burn-in racks before packing
8. Shipment - cartons leave FOB, CIF or DDP according to the agreed logistics terms

Customer Testimonials

Here is what the people who actually ordered said afterward.

• Somchai Prasert (EV Charging Station Distributor, Bangkok, Thailand): "We stopped counting burned sockets because there are none left to count."
• Nguyen Hoang Minh (Charge Point Operator, Ho Chi Minh City, Vietnam): "Our support line used to get billing-dispute calls weekly. That queue has gone quiet."
• Budi Santoso (E-Mobility Service Provider, Johor Bahru, Malaysia): "The station we field-tested through the rainy season is the station we sell; our listing says IP54 and the field record proves it."

Frequently Asked Questions

Q: Why two load groups instead of one?

A: If a fault or overload hits one group, the other ten sockets keep charging, and each group draws against its own feeder cap.

Q: Can we bill riders per kWh?

A: Yes, every socket meters consumption and the station exports daily settlement files for wallet or cash reconciliation.

Q: How many stations can one CSMS manage?

A: There is no fixed limit; each WL-CS20 registers as one charge point with 20 connectors over OCPP 1.6J.

Q: What is the installation footprint?

A: Twin cabinets bolt side by side on a 1.6m wall span or back to back on a pedestal frame.

Q: Can we start with one cabinet and expand later?

A: Yes, the twin-cabinet design ships as one group first, with the second cabinet adding on the same feeder.
